Are we related?

My grandfather, Vito Francesco Abrusci, was born in Acquaviva Delle Fonti on August 24, 1888. He immigrated to the U.S. and settled in Oakland, CA. He married Rosa Porreco on January 23, 1913. They were married in Acquaviva. I am interested in finding out if the Abrusci's are related since the name is not a common name, in fact the name is very rare. If you believe we might be related, please respond. Thank you
